The FORALL statement issues a series of INSERT, UPDATE, or DELETE statements, usually much faster than an equivalent FOR loop. The FOR LOOP statement ends when its index reaches a specified value, or when a statement inside the loop transfers control outside the loop or raises an exception. Its scope is the loop itself; you cannot reference the index outside the loop. Code line 2: Printing the statement "Program started". Code line 6: Keyword 'END LOOP' marks the end of execution block. Each FORALL statement may contain just a single DML statement. It requires some setup code, because each iteration of the loop must use values from one or more collections in its VALUES or WHERE clauses. and Oracle FORALL is defined as "The keyword FORALL instructs the PL/SQL engine to bulk-bind input collections before sending them to the SQL engine.

Example 12-8, "DELETE Statement in FORALL Statement" Example 12-9, "Time Difference for INSERT Statement in FOR LOOP and FORALL Statements" Example 12-10, "FORALL Statement for Subset of Collection" Example 12-11, "FORALL Statements for Sparse Collection and Its Subsets" Example 12-12, "Handling FORALL Exceptions Immediately" ; Code line 3: Keyword 'FOR' marks the beginning of the loop and loop_variable 'a' is declared.It now will have the value starting from 1 to 5; Code line 5: Prints the value of 'a'. An undeclared identifier that names the loop index (sometimes called a loop counter). After each iteration, the loop index is incremented. PL/SQL declares the FORALL iterator (indx on line 30 in Listing 4) as an integer, just as it does with a FOR loop. The FORALL statement issues a series of static or dynamic DML statements, usually much faster than an equivalent FOR loop. index_name. FORALL Statement. FORALL Statement. For more information, see "Reducing Loop Overhead for DML Statements and Queries with Bulk SQL". Although the FORALL statement contains an iteration scheme, it is not a FOR loop. The loop body is executed once for each integer in the range defined by lower_bound..upper_bound. For more information, see "Reducing Loop Overhead for DML Statements and Queries (FORALL…

With each iteration of the FOR LOOP statement, its statements run, its index is either incremented or decremented, and control returns to the top of the loop.

It requires some setup code, because each iteration of the loop must use values from one or more collections in its VALUES or WHERE clauses. If your loop contains two updates and a delete, then you will need to write three FORALL statements. Its syntax follows:
